Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603676, here are decompositions:

19 + 31603657 = 31603676
67 + 31603609 = 31603676
109 + 31603567 = 31603676
157 + 31603519 = 31603676
283 + 31603393 = 31603676
367 + 31603309 = 31603676
823 + 31602853 = 31603676
883 + 31602793 = 31603676

Showing the first eight; more decompositions exist.
